Diospyros australis (Black Plum) is a valuable Australian rainforest tree known for its attractive foliage, distinctive black bark, and edible fruits. This small to medium-sized tree features glossy, dark green leaves that create a dense canopy, with new growth often appearing bronze or reddish. The tree produces small, inconspicuous flowers followed by round, fleshy fruits that ripen from green to dark purple-black, providing an important food source for native birds and wildlife.
Well-suited to subtropical and warm temperate climates, the Black Plum thrives in well-drained soils and can tolerate both full sun and partial shade. Its compact size and non-invasive root system make it suitable for urban gardens, rainforest restoration projects, and habitat planting. This tree is particularly valued for its ornamental bark, which becomes increasingly fissured and attractive with age.
